Abstract
A color filter capable of being uniformly formed without any deformation of a light-permeable anode conductor and prevented from being adversely affected by etching for formation of the anode conductor. A light-permeable anode substrate free of any deformation is uniformly formed thereon with anode conductors, on which color filters are formed of a mixture of a composite oxide pigment and a conductive material so as to cover the anode conductors. The color filters each are formed by arranging a color filter material in a predetermined pattern, followed by calcination. Then, phosphor layers are deposited on the color filters. The phosphor layers are electrically connected through the conductive material of the color filters to the anode conductors. A thickness of the color filters and a particle diameter of the conductive material are determined to be substantially the same, so that the color filters exhibit conductivity only in a direction of thickness. Thus, contact between the color filters adjacent to each other does not cause electrical connection therebetween.
